Exhibit 99.1 CONTACT: MIKE EL-HILLOW EXECUTIVE VICE PRESIDENT, CHIEF FINANCIAL OFFICER ADVANCED ENERGY INDUSTRIES, INC. 970-407-6570 MIKE.EL-HILLOW@AEI.COM FOR IMMEDIATE RELEASE ADVANCED ENERGY REPORTS FIRST QUARTER 2003 RESULTS FORT COLLINS, COLORADO (APRIL 17, 2003)-Advanced Energy Industries, Inc. (Nasdaq: AEIS) today reported financial results for the first quarter ended March 31, 2003. Advanced Energy offers a comprehensive suite of process-centered solutions critical to the production of semiconductors, flat panel displays, data storage products, architectural glass, laser, medical and other advanced product applications. For the 2003 first quarter, revenues were $56.2 million, up 31 percent from $42.9 million for the first quarter of 2002 and down 2 percent from $57.4 million for the fourth quarter of 2002. Net loss for the first quarter of 2003 was $8.6 million or $0.27 per share, compared to a net loss of $8.7 million in the first quarter of 2002, or $0.27 per share. This compares to fourth quarter 2002 net loss of $22.0 million, or $0.68 per share. Both the first quarter of 2003 and the fourth quarter of 2002 had charges associated with the operational changes that the Company has implemented in response to reduced market demands. In the first quarter of 2003, these charges, net of tax, totaled $1.1 million or $0.04 per share, principally attributed to restructuring charges, and $14.2 million in the fourth quarter of 2002 or $0.44 per share. Excluding these charges, the 2003 first quarter net loss would have been $7.5 million or $0.23 per share and the fourth quarter 2002 net loss would have been $7.8 million or $0.24 per share. Doug Schatz, chairman and chief executive officer, said, "As we expected, the first quarter of 2003 presented continued sluggish demand in our end markets, especially the semiconductor capital equipment sector. Our order pattern has remained essentially linear since late in 2002 and there are no indications that this will change in the near term. While the industry has remained suppressed, we continue to find ways to increase our addressable markets. We have done this by continuing our focus on the development of products and technologies that leverage the application value of the plasma for our customers. By focusing our research and development on our core product groups, we believe we can realize more high-value revenue possibilities, continue to develop the most reliable products at the lowest possible cost and have the quickest time from concept to commercialization." "Based on information we have today, we anticipate second quarter revenue in the $56 to $60 million range and a loss per share range of $0.18 to $0.21 that reflects continued improvements from our operational changes", said Mr. Schatz.
